Compared with the relatively good durability of angioplasty and stenting procedures within the extracranial carotid artery, the high incidence of restenoses appears to be a major drawback of intracranial stenting. Recent studies suggested that especially younger patients treated with self-expandable stents within the anterior circulation have a higher risk for this complication. Considering about 33% of restenoses were symptomatic (TIA or stroke), decreasing restenosis rates after intracranial stenting became the key issue for improving the clinical feasibility of this treatment strategy.
